Description
31CrMoV9 Round Bar
31CrMoV9 Round Bar is a nitriding steel which has at least 2.3%Cr,0.15%Mo,0.1%V as strengthening alloy elements.
Due to its high wear resistance,it is mainly used in the automotive industry and general components mechanical engineering.30CrMoV9 is difficult to weld and therefore should not be used in weld constructions.It can attain surface hardness of 800 HV after nitriding.31CrMov9 is directly involved the nitriding steel 30CrMoV9 (DIN1.7707)
31CrMoV9 is a steel which in general is intended for the fabrication of quenched and tempered parts, which are generally machined and subsequently nitrided.
